Toshiba P200 laptop, screen flickers constantly if the top is opened past 50/60 degrees. Removed all the screws but could not separate the key board etc to check out the connections. Out of warranty. Any help would be appreciated.

As in this model?

The Display Assembly is laid back to a point, that you can access the two bottom screws. Isn't a direct 90 degree position with the screwdriver. More like 60 degrees.

No?

Then the Top Cover (Palm Rest Cover) has to be removed, in order to access.

Don't forget to remove ALL power. AC adapter and Battery.

It should be a Problem of a loose conection.
if you feel you are good to take it apart there are a lot of tutorials on the web in how to take it apart and reattach the flex cable. (maybe even change it)
otherwise take it to a laptop specialist

An LCD screen cannot produce enough light by itself. It needs a Backlight to help illuminate the screen.

Power for the Backlight is produced by an Inverter. An Inverter also provides power for the LCD screen.
It reduces voltage for the Backlight, and increases Voltage for the LCD screen, from the laptop's power.

Most of the time a dark LCD screen can be attributed directly to a bad Inverter. (Around 90 percent)

A Backlight is a CCFL.
Cold Cathode Fluorescent Light.
VERY similar to the fluorescent lights you see used in residential, and commercial applications.
(Homes, and businesses)
Only on a MUCH smaller scale in physical size, and needed power to operate.
When a Backlight goes bad, it just goes all at once. Not goes dark as you have stated.

(Your statement meant to me that you power on the laptop, the LCD screen shows well, then goes dark)

NOTE*
1) ALL power removed from the laptop before beginning.
AC adapter (Charger), and Battery.

2) The screws you will remove, may have screws that look alike, but are NOT.
Do Not mix them up.
For this reason it is suggested to use a multi-compartment container, and label the compartments for where the screws came out of.
You can use a clean egg container, and label the individual egg holders, in a pinch.

IMHO it isn't hard to perform this repair, and you can do it. Save yourself money.

The wire that connects the lid with the motherboard might be damaged, but not completely damaged as you use your screen normally, so i recommend that you check this connection.

3g card? if i recall correctly there is a slot on the top of the motherboard for that labeled 3g. obviously that would require the top cover to be removed.start with the screws under the battery that releases the plastic strip above the key board, remove the key board and you should see the slot underneath

Hello, I have a Toshiba Satellite P200-rt2 that has the same issue. They told me that there's a part that connects to the monitor that needs to be replaced. It costs as much as the computer does. So, I have bought a new one. I want to know if there are other people with this issue. Maybe we can go to Toshiba with this issue.

you have to rip apart everything carfuly, remove the four screws behing the runner covers on the screens lid.

The problem is the pathway from the chip to the internal display. The Nvida chip has several output lines, many of which go to the external monitor but many also go to the internal display connector. I had a case recently where the screen worked fine until the customer opened the display past 90 degrees. What was actually happening was that enough presure was being applied by the internal connector to lift the mother board connector off the mother board. Apparently the factory solder job wasn't too good. We were lucky in that we used a high intensity heat source which remelted the solder on the connector. Whoever was dilligent enough to be to test your screen and cable should be able to trace the signal from the chip out.

press ctrl + alt + pageup key or ctrl+****+pageup
then check
or boot you system in safe mode then uninstall the graphic driver then boot normal install it again

For AS 3680,
